Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530256, here are decompositions:

5 + 530251 = 530256
7 + 530249 = 530256
19 + 530237 = 530256
29 + 530227 = 530256
47 + 530209 = 530256
53 + 530203 = 530256
59 + 530197 = 530256
73 + 530183 = 530256

Showing the first eight; more decompositions exist.
